Abstract

Problem solving in mathematics is a basic and fundamental ability that a person must master. However, previous research shows that students' problem solving abilities still tend to be in the medium and low categories. Many factors can cause students' low problem solving abilities, including number sense ability. The aim of this research is to describe linear programming problem solving for mathematics education students with high number sense abilities. This research is a descriptive qualitative research involving 36 third year Mathematics Education Study Program students who have taken linear programming courses. The instruments used were number sense ability test questions, problem solving test questions, and interview guidelines. The results of this research obtained information that there were 6 students with high number sense abilities, all of whom only reached the medium category in problem solving. In general, students in this category do not write complete information regarding the constraints of linear programming problems at the information gathering stage. In addition, students also do not carry out the re-checking stage of solving the problem because they feel confident with the answer given. However, this solution is not correct

Abstract

The non-linear mathematical model of the break even point (BEP) problem is difficult to solve analytically to obtain an exact solution, so the alternative is to solve it numerically. This research aims to solve the BEP problem and measure the effectiveness of Brent's method compared to other solution methods based on error and number of iterations. This research is an applied type whose implementation procedures include preparation, implementation, program testing, program revision, analysis, and conclusion. The errors of Brent’s, secant, false position, and bisection methods in solving the BEP problem are 0.00118; 0.00893; 0.64485; and 0.89119, respectively. While the number of iterations from several checks are 52, 53, 91, and 101, respectively. Therefore, it can be concluded that the Brent’s method is more effective than the other three methods.

Abstract

The purpose of this study is to determine how the Game Based Learning model using the Quizizz application influences the interests and learning outcomes of grade VIII students of SMPN 3 Jonggat in the 2024/2025 academic year. The results of the Manova analysis obtained a significance value of 0.002 < 0.05, which means that H1 is accepted or there is a difference in the average interest and mathematics learning outcomes of students in the experimental class who use the game based learning model with the Quizizz application and the control class who use the conventional model. The results of the t test show a significance value of 0.006 < 0.05, which means that H1 is accepted or there is a difference in the average learning interest of the experimental class and the control class with the average value of the experimental class being 72.25, which is higher than the control class, namely 70.65. Likewise, there is a difference in the average mathematics learning outcomes of experimental class students, which is higher than that of the control class, with the average score of the experimental class being 85.01, which is higher than the control class, namely 71.35. Because there is a difference between the average of the experimental class and the control class and the average score of the experimental class is superior to the control class, there is an influence of the use of the game based learning model using the Quizizz application on the interest and learning outcomes in mathematics for class VIII students at SMPN 3 JONGGAT for the 2024/2025 academic year.
